During the second post-war period, Marilyn Monroe harmonizes the balance between innocence and seduction: the blonde hair and the delicate features are echoed by full lips and dangerous curves. In a Western world that was still licking the wounds of war, the economic meagreness was counterbalanced by the generous and impeccable beauty of the Pin-up girls; it is no accident that when the wellness becomes phenomenon of a mass that has both abundant money and abundant bodies, the thin Twiggy, thanks to the mini-skirt by Mary Quant, becomes the icon of a city like London, that was constantly in a state of ferment, and was far away from the extended lethargy of the bourgeois salons. Thanks to Jane Fonda, beauty is reinvented in a toned and muscular body. During the excessive Eighties, the beauty becomes aristocratic thanks to the myth of Lady Diana, the people’s princess, but that at the same time was so unreachable from it. Cindy Crawford and Naomi interpret the bionic woman of the 90s, which today is overtaken by the imperfect androgyny of Kate Moss. Man, too, had trouble to find a common denominator. He searched it in the heroism of the Greek Doryphoros, in the exaltation of the macho man, that never has to ask, and that later was renegade by the object-man, celebrated by Richard Gere in American Gigolò.
